POWER-TRANSMITTING MEANS.

Specification of Letters Patent.

To a/ZZ whomJ 7115 ntctg/ concern:

Be it known that I, VILLIAM D. GOFF, a citizen of the United States,residing at Joplin, in the county of Jasper and State of Missouri, haveinvented a new and useful Power- Transmitting Means, of which thefollowing is a specification.

This invention in one aspect relates to means for converting rotary intoreciprocatory motion, and while particularly useful as pum -operatingmechanism is undoubtedly capa le of successful employment for otherpurposes.

One of the principal objects is to provide novel means of a simplenature whereby rotary driving power is converted into reciprocatingmotion for operating a plurality of reciproeatory memb ers-as,forinstance, pumpplungers-the said members being so arranged that theypractically balanee each other, and thereby eliminate to a great extentthe shock due to the change of direction of movement.

A further wobject is to provide mechanism wherein either reciprocatorymember can be disconnected from the driving means and to provide meansthat can be arranged to act as a counterbalance in place of the memberso disconnected, the eounterbalancing means being also disposed so thatit may be made to act in case the members do not of themselves eounterbal ance.

The preferred embodiment of the invention is illustrated in theaccompanying drawings and is in the form of pump-operating means.

In the drawings, Figure 1 is a perspective view of the mechanism. Fig. 2is a side elevation of the crank connections between the driving anddriven elements and illustrating their action. Fig. 3 is a plan viewshowing the clamping means for the well-easings. Fig. 4 is a verticalsectional view through the rock-wheel. Fig. 5 is a top plan view of thesame. Fig. 6 is a cross sectional view through the counterweight and itssupport.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated a suitable frame 7 is employed, comprisinglongitudinal and cross beams bolted or otherwise secured together. Onone end of the 'frame is journaled a driving-shaft S, that isdisposedtransversely of the frame and carries at one end a driving-pulley 9 andat the other end a crankarm 10, provided with a series of openings 11. Afly-wheel 12 is preferably mounted on the drive-shaft between thelongitudinal beams of the frame. A rock-shaft 13 is journaledtransversely on the other end of the frame and carries at one end acrank-arm 14, said crank-arm being longer than the crank-arm 10. Apitman 15 is connected to the free end of the arm 14 and has anadjustable connection 16 with the crank-arm 10. The connection 16 isarranged to be placed in any of the openings 1 1, so that the end ofthepitman secured thereby can be placed at different distances from theaxis of rotation of the crankarm and of the drive-shaft 8. By thisarrangement it will be clear that if the driveshaft S is rotated `fromany suitable source of power the rotating crank l() will cause abackand-forth swinging movement of the pitman 15. The crank 14. beinglonger than the crank 1() will consequently swing back and forth, andthus the shaft 13 will be rocked.

Secured to the opposite end of the rockshaft I3 to that carrying thecrank-arm I4 is a rock-wheel 17, disposed at one side of the iframe andhaving a series of peripheral grooves IS. (Shown more particularly inFig.) On opposite sides of this wheel are located oppositely movingreeiprocatory members I9, which in the present embodiment are pumpplunger-rods and are vertically disposed, though, as already stated,they may be devices employed for other purposes. The members 19 areshown as extending into well-casings 20, clamped by bars 2l and bolts 22to one side of the frame. The upper ends of the easings are surroundedby suitable discharge-spouts 23. Doubled cables 24 have their endsadjustably and detachably clamped, as shown at 25, to the upper portionof the wheel 17, said cables passing through openings 26 in the upperportion of the pulley and extending downwardly in the outer peripheralgrooves I8. The lower portions of these cables extend on opposite sidesof the reciprocatory members 19 and pass about cross-pins 27, thatextend through the members 19 and project on opposite sides of the same.Upwardly-extending single eables 2S are adjustably and detachablyclamped, as shown at 29, to the lower portion of the wheel and, passingthrough an opening 30 therein, extend upwardly in the central groove.The upper ends oi' the cables 28 are detachably fastened, as shown at31,

v to eyes that are carried by the upper ends of IOO lIO

the reciprocatory members. It will be observed that by this arrangementthe reciprocatory members move in opposite directionsA upon the movementof the roclcshaft, being elevated by the doubled or looped cables andbeing moved downwardly by the single cables 28.` Moreover, it will beapparent that either member may be disconnected from the wheel.

In order to oounterbalance either member when operating singly, thefollowing mechanism is preferably employed: A walkingbeam 32 is suitablysecured to an intermediate portion of the rock-shaft 13 and hasoppositely-extending arms. A longitudinal guideway or track 34,dovetailed in crosssection, is formed upon the upper portion of thiswalking-beam, and slidably mounted on the track is a counterbalancingdevice in the form of a weight 35, that is thus movable to positions onopposite sides of. the axis of movement of the shaft 13. A suitablesetscrew 36, carried by the counter'weight, serves to hold it in anydesired position.

From the above it will be apparent that if the drive-shaft is rotatedthe rock-shaft will be moved, and because of the connection between thewheel and the reciprocatory members said members will be alternatelymoved in opposite directions. If these members properly oounterbalance,the weight 35 is of course placed directly over the rock-shaft 13; butif one should be heavier than the other the weight may then be moved inorder to assist the lighter in counterbalancing the heavier. If for anyreason one of the beams or reciprocatory members is inoperative and itis desired to use the other alone, the beam or member is disconnected bydetaching the cables and the weight 35 is arranged on the proper arm ofthe walking-beam, so that it will counteract or counterbalance theweight of the operating member.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
